我有表:司機,driver_negotiation,base_negotiation和團隊Yii CDbCriteria:如何從AR中的「3rd」表中獲取價值?
在DriverController模式,我想獲得TEAM_ID(它位於base_negotiation)驅動程序與談判。
在驅動程序模式,我有:
'driverNegotiation' => array(self::HAS_ONE, 'DriverNegotiation', 'driver_id')
而且在DriverNegotiation:
'baseNegotiation' => array(self::BELONGS_TO, 'BaseNegotiation', 'base_negotiation_id')
在DriverController我建立類似:
$criteria=new CDbCriteria(array(
'condition' => 'baseNegotiation.team_id=13',
'with' => 'driverNegotiation',
'together' => true,
));
,但我得到:
Column not found: 1054 Unknown column 'baseNegotiation.team_id' in 'where clause'.
The SQL statement executed was: SELECT COUNT(DISTINCT `t`.`id`) FROM `driver` `t`
LEFT OUTER JOIN `driver_negotiation` `driverNegotiation` ON
(`driverNegotiation`.`driver_id`=`t`.`id`) WHERE (baseNegotiation.team_id=13)
所以我可以從driver_nagotiation表中得到所有的東西,但是沒有任何東西從一個表中得到。
我需要使用連接來獲得正確的東西還是有更好的方法?
